Dialysis-dependent renal failure in patients with myeloma can be reversed by high-dose myeloablative therapy and autotransplant

To evaluate the role of high-dose melphalan and autologous transplant (AT) in reversing dialysis-dependent renal failure, 59 patients still on dialysis at the time of AT were analyzed. A total of 37 patients had been on dialysis < or =6 months. A 5-year event-free and overall survival rate of all patients after AT was 24 and 36%, respectively. Of 54 patients evaluable for renal function improvement, 13 (24%) became dialysis independent at a median of 4 months after AT (range: 1-16). Dialysis duration < or =6 months prior to first AT and pre-transplant creatinine clearance >10 ml/min were significant for renal function recovery: 12 of 36 (33%) < or =6 months vs one of 18 patients (6%) >6 months on dialysis recovered renal function; 10 of 26 (38%) with >10 ml/min vs three of 28 (11%) with < or =10 ml/min of creatinine clearance (both P
